The Scariest Moment in RHONYC History, and More Shocking Revelations from Ramona Singer's New Book, Life on the Ramona Coaster

Real Housewives of New York City viewers all raised our eyebrows last night when Ramona Singer brought back a guy to their Turks and Caicos vacation home, left him sleeping naked in Heather's room, and then acted all "who, me?" when Heather became irate. But naked-sleeping-man-gate is nothing compared to some of the reveals in Singer's new tell-all book, Life on the Ramona Coaster—here are five of the most shocking.

She threatened to kill her father as a child. Ramona has spoken on RHONYC about her upbringing, but she goes more in-depth in her book, describing how her father was emotionally and physically abusive to her mother. At one point, she intervened by grabbing a knife. "I point the blade directly at his face and scream, 'Stop it. Stop it right now or I swear I will take this knife and shove it into your neck,'" Ramona writes.

But her childhood has helped her on Real Housewives. "It's easy for me to block out the cameras," Ramona writes. "Probably because, growing up, I had to block out all the noise in my family. I shut the cameras out, just like I shut out my father's yelling.

She believes the success of RHONYC played a part in the breakup of her marriage. "Things started to go downhill when Mario found out how much I was making for season six of the Real Housewives," Ramona writes. "Mario had just turned sixty and his business was struggling. [But] his wife had become famous and was earning a great salary. He was on a path leading him farther and farther away from our marriage."

One of the scariest RHONYC moments? Kelly Bensimon's freakout on St. John. So scary, in fact, that they called Jill Zarin that night for help. "I told her, 'Kelly needs you. She's going to be on a plane. You should meet her in New York,'" Ramona writes. Even Bethenny Frankel, who had issues with both Jill and Kelly at the time, got on the phone and said, "Jill, this is not about the show, we're worried about Kelly."

And she finally admits to having her breasts done. Bethenny has been calling BS on Ramona's denial on the show, but in her book, she cops to it. "Recently, I did have my breasts done," she writes. "I've worked hard to maintain a youthful look, and I'm proud I was able to put off surgery as long as I have."
